By the way, if two devices with the same EUI64 are powered

more than one removed from each other.
I thought that for a while, too.
However, a registration with the same TID is defined to cause a
conflict.
So if the nodes don't manage to exactly synchronously alternate in
losing packets, eventually the conflict will be detected.
Unless we require hosts to be awake enough to defend their addresses,
there is no discernable difference between a reboot and a conflict of
a new node with a sleeping node. So it will be hard to enable
detection immediately after switching on the colliding node.
